文摘

New mortars prepared by electrostatic dry deposition of nanosilica and microsilica. Optimal hydration degree and C-S-H gels percentages for mortars with 10% of addition. Enhanced compressive strength of the cement mortars with additions. Lower chloride migration coefficients and higher electrical resistivity values. Microstructurally, the role of ettringite in durable properties is evaluated.
